[SCSI] lpfc 8.3.8: BugFixes: SLI relates changes
Fix hardware/SLI relates issues: - Handle XB bit so that ELS XRIs are not prematurely released. - Handle XB bit so that FCP XRIs are not prematurely released. - Define new security SLI Commands. - Remove unused security SLI commands - Skip receive data size parameter check on received FLOGI. - Added LPFC_USE_FCPWQIDX flag to iocb to force SLI layer to submit abort WQE on same WQ as the command WQE.
